By 2047, The Installed Capacity Of Seawater Desalination Systems Will Have At Least Doubled From 2027 Levels, Driven By Global Water Scarcity Pressure And Led By The Middle East And Africa Region.

Global Growth in Desalination Capacity

Pressure on freshwater resources worldwide is increasing every year. Climate change, rapid population growth and urbanization are making water supply more fragile, especially in arid and semi-arid regions. Under these conditions, seawater desalination systems stand out as a strategic option that reduces dependence on traditional water sources. Middle Eastern and North African countries have invested in this technology for decades, becoming the region with the largest installed capacity in the world. The fact that water scarcity is not limited to this region but is spreading to sub-Saharan Africa, South Asia and even the Mediterranean coast turns desalination into a global infrastructure issue.

The main factor supporting the growth of the desalination market is that seawater does not depend on unpredictable weather conditions such as rainfall or snow. This offers water planners a long-term and predictable supply security. Technological advances, especially the increasing efficiency of reverse osmosis membranes and lower energy consumption, have historically pushed unit costs down. The spread of facilities integrated with renewable energy also reduces dependence on fossil fuels, making desalination more sustainable. Large-scale projects in the Middle East and a growing number of small and medium-sized facilities in Africa stand out as regional engines of capacity growth.

The doubling of installed capacity by 2047 to at least twice the 2027 levels can be considered a reasonable extension of current trends. Rising global water demand, higher capacity utilization rates of existing facilities and accelerating new investments support this forecast. In particular, the fact that governments in the Middle East and Africa view water security as a national security issue encourages public and private sector investment. In addition, the orientation of the industrial and agricultural sectors toward desalinated water increases demand not only for drinking water but also for production processes. When these dynamics are evaluated together, it appears highly likely that daily production will exceed twice the 2027 values by 2047.

To verify the forecast, it is necessary to look at global desalination capacity reports published in 2047. If these reports confirm that daily production is at least twice the 2027 values, the forecast is considered to have come true. The regional distribution of capacity growth is also important. The leadership of the Middle East and Africa will show how intensely the pressure of global water scarcity is felt in these geographies. In summary, as long as water scarcity, technological progress and investment trends move in the same direction, desalination capacity can be expected to double.
